Patent CA-2354781-A1 (CA)
Inventor: SCHNEIDER GABRIEL
IPC: F41G5/26
Filed: 2001-08-07
Abstract: Method and device for correcting shooting errors. Such shooting errors are to be corrected that are occasioned by a movement of a barrel (12) of a gun (10) out of its nominal position in consequence of a movement of a lower carriage (18) when a shot is being fired. By means of an angle meter element, an error angle is determined along which the lower carriage rotates about the vertical axis (Z). An error signal is obtained from the error angle. Said error signal is utilized to change the azimuth of the barrel of the weapon (12) in order to compensate an error of the azimuth and of the elevation occasioned by the rotation of the lower carriage (18) about the vertical axis (Z).
Patent CA-2356869-A1 (CA)
Title: Method and devices for coding or decoding an audio signal or bit stream
Inventor: BRANDENBURG KARLHEINZ
IPC: H04H20/00
Filed: 1998-12-28
Abstract: In order to obtain a coded bit stream in a method for coding an audio signal , two time-discrete audio signal scan values are transformed in the frequency range with the purpose of obtaining spectral values. Said spectral values ar e coded using a code table with a limited number of code words having differen t lengths in order to obtain spectral values coded by code words, the length o f a code word assigned to a spectral value being shorter if the probability of  occurrence of the spectral value is higher. A raster is then determined for the coded bit stream, wherein the raster has equidistant grid points and the  space between the grid points depends upon the code table(s) used. In order to obtain error-free Huffman encoding, priority code words representing given spectral values that are more significant than other spectral values from a psychoacoustic viewpoint are disposed in the raster in such a way that the beginning of the priority code word coincides with a grid point.

Patent CA-2371506-A1 (CA)
Title: Granular material conveyor
Inventor: LEPAGE CHARLES
IPC: B65G33/24
Filed: 2002-02-13
Abstract: Disclosed is an improved conveyor. The invention provides an apparatus for conveying material having an elongated tube with an input end and a discharge end, an intake hopper having a front end secured to the input end of the tube and an endless belt for conveying material from the intake hopper to the discharge end of the tube. Mounted within the intake hopper is at least two augers positioned above the endless belt and external to the input end of the tube. The endless belt and the augers are driven with appropriate drive means. Rotation of the augers conveys granular material in the hopper toward the input end of the tube so as to flood feed the input end of the tube. The granular material is then carried to the discharge end of the tube by the belt. In addition, the invention provides for the mounting of the augers to permit adjustment of the location of the augers within the intake hopper as well as facilitating easy removal and replacement of the augers.      Further, the speed at which the augers are to be driven is also adjustable. The foregoing provides great flexibility with respect to different applications which the conveyor will be used for. The invention also provides for additional feed augers located toward the rear of the hopper and adapted for moving material from the sides of the hopper towards the center where it will be transported by the belt and augers to the input end of the tube.
